Huchel | June 26, 2001 |
A tubular film package comprising a tubular film provided with a tear strip secured upon an outside surface of the film. The tear strip is defined by a longitudinal edge of the film and a heat seal joint provided in the film essentially parallel to the longitudinal edge. The film is further provided with at least one slit running from an end of the film to the heat seal line so that pulling of the strip away from the package commencing at the slit causes film to separate proximate the heat seal line thus opening the package.
